I have developed a small application that packages recent updates of websites into a periodical, similar to what instapaper does.

The periodical renders fine on the Kindle Previewer application and works on a Kindle Paperwhite 3G, except that somewhere in the middle of the ebook the Kindle freezes when turning the page. Looking through the source code and the documentation, I don't see anything suspiciously wrong at that particular page. (Source code and mobi of a 10 page periodical is attached)

I have switched on the debug mode on the Kindle and looked through the logs, but can't find any further details on where the problem is: the Kindle boots normally, the last things dumbed is "140101:202356 winmgr[1246]: D lua:dbg::flashing rect 0, 0 :: 758 x 1024 -- 12".

What is a better way to debug this? Thank you very much in advance for any hints

For laughs, I tried to make an ePub in Sigil using your html files, and had great troubles due to errors in the encoding. You seem to have forgotten the closing / for the meta tag in item1, 2 and 3, and I also had to add in the <?xml> and <html> ... </html> sections to each of those.
